write a short note on the flow of energy in an ecosystem
Answers
Explanation:
Energy flow is the flow of energy through living things within an ecosystem.All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain.Each of the levels within the food chain is a trophic level.In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. The arrows in the food chain show that the energy flow is unidirectional, the head of the arrows show the direction energy is moving in, and that energy is lost as heat at each step along the way.
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
hope it helps ✌✌
